12 Claims.

The present invention relates to an apparatus for handling or decorating articles.

The principal object of the invention is to provide an apparatus for automatically decorating Ii tumblers and similar articles which will apply to the articles a closed band or series of closed bands of similar or contrasting colors. a right or left-hand continuous or interrupted spiral band or series thereof, or any combination or 10 multiple of such closed, interrupted or spiral bands.

The machine comprising the present invention is designed as an improvement over the type of handing machine disclosed in United States re-- 15 issue: patent to Harold R. Schutz, 20,277, Febru ary 23, 1937.

Other objects of the invention will become apparent hereinafter.

-of the chuck 2|.

(our-1c) r I mounted the chuck assembly A and locking mechanism B and on the other end of which is slidably mounted a counterweight [4. The frame C is pivoted medially of its ends to a pair of brackets I5 by means of bearing plates it (Fig. 1) 5 which are removably secured by cap screws IT to the frame C. Trunnions l9, secured in the brackets l5, extend centrally through slots 20 formed in the frame C and through the plates I6 and form the pivotal connection for the frame The chuck assembly A comprises a tapered cylinder 2| (Fig. 3) or chuck over which the tumbler to be decorated is placed with its rim bearing against an abutment flange 22. The chuck 2! is mounted upona shaft 23 which is supported in a ball-bearing assembly 2t secured to the forward end of the frame 0 at one side thereof and from which there projects a hendle 25.

The locking mechanism 13 comprises a supporting arm 26 which is pivoted to the forward end of the frame C at the other side thereof and which extends to a point adjacent thejsmall end A locking lever 21 carrying a handle 28 is pivoted medially of its ends to a bracket 29 on the arm 26 and one end thereof is bent laterally and is provided with a spherical bearing surface 30. A coil spring 3| positioned between the other end of the lever 21 and the arm 26 causes the bearing surface 30 to press 30 against the bottom of the tumbler T to maintain the same on the chuck. By means of the handle 28, the lever 21 may be moved horizontally so as to bring the bearing surface 30 out of contact with the tumbler T and then swung upwardly together with the arm 26 in order that substitution of tumblers on the chuck may be effected.

The reservoir D is supported upon the table portion it directly beneath the chuck assembly A.: A partition 35 (Fig. 1) extending centrally across the reservoir parallel to the axis of the chuck 2| divides the reservoir into two containers 38 and 31 adapted to contain difierently colored enamels.

A pair of agitators 38 (Fig. 3) for the liquid 5 enamels are pivoted in the side walls of the reservoir D and depend into the respective containers 3B and 31. Crank arms 39 formed on the agitators 38 exteriorly of the reservoir are attached to a connecting rod 40 which is actuatedby an oscillating lever 4| whichis in turn actuated through a pin and slot connection from a cam cylinder 42 mounted on a shaft 15 as is more clearly shown in; the above mentioned Schutz patent.

The shaft 45 and a shaft 46 (Figs. 1, 2 and 3) are. positioned between the chuck assembly A and the reservoir D, extend transversely of the machine, overlie the respective containers 3S and 5 3i, and are journalled in bearing supports dli secured to the table it. The shaft 45 is positively driven from a gear reduction device 48 and motor M through a system of belts and pulleys 49 and gearing 50. The shaft 46 is adapted to receive its motion by contact with the tumbler T on the chuck 2!, but during substitution of tumblers is kept in motion by means of a turbine 5i mounted thereon which derives its motion from a jet 52 connected to a source 53 of compressed air. Thus a yielding torque may be said to be constantly applied to the shaft 66 to yieldingly continuously rotate the same for a purpose that will presently appear.

Each shaft 45 and 46 has slidably keyed thereto a sleeve M (Fig. 7) upon which is mounted one of the banding disks E. Each disk is in the form of a steel ring, the outer peripheral edge of which has a width corresponding to .the width of the spiral band to be applied to the tumbler T. The

disk E is frictionally held between a pair of disks 54 which are clamped to the opposite sides of a hub 55. between a circumferentially grooved flange 56 formed on the sleeve and a similarly grooved collar 5i by means of a clamping nut so it. A curved band spring 59 positioned between the hub 55 and disk E permits the disk to yieldingly bear against the surface of the tumbler and automatically compensate for any irregularity in the surface 'of-the tumbler. The disks E dip into the enamel composition contained in the respective containers 36 and til of the reservoir D.

When the frame C and chuck assembly A are in decorating position, the tumbler T on the chuck 2| is nested between the two banding disks 40 E on the shafts and M respectively. Means is provided for sliding the rotating disks E longitudinally of their respective shafts in opposite directions to simultaneously apply ascending and descending spiral bands to the surface of the 45 tumbler as shown in Fig. 10. Accordingly, the sleeves M are each movable longitudinally of the shafts 45 and 46 under the impelling action of a bifurcated bracket 66 (Figs. 3 and '7) having forks 5| which straddle the grooved flange 56 and grooved collar 57!. The brackets -39 are secured to carriages t2 and $3 or rack bars which are mounted in slideways (it provided in upstanding ribs 65 formed on the table it at opposite sides thereof.

A central bearing $6 is formed integrally with and depends from the table it and is provided with webs 67 having bearings dd formed at their outer ends. Slots tit (Figs. 1 and 2) formed in the ribs 65 provide clearance for a pair of 60 rack shifting gears 6s and iii which are mounted on shafts H supported in the bearings 68 and which mesh in their upper regions with rack bars 62 and 63 respectively. The gears (39 and i6 mesh in their lower regions with horizontal teeth 65 provided on a pair of rack bars l2 and i3 mounted in slideways It formed in the framework i2. An oscillating gear lb, suspended from the hub 56,

bridges the distance between the rack bars E2 and lating bell crank lever 76 (Fig. 2) mounted upon 7 the upper end of a standard 11. One arm 01 the lever I6 is connected by a link I8 to an eccentric point on the gear 15 while the other end thereof is provided with a cam roller 19 which is in contact with the surface of a rotating cam plate 80 (Figs. 2 and 4) secured to a shaft 8! rotatably mounted in a bearing 82 formed on the standard W. A spring 83 serves to restore the gear I5 to its initial position and thus cause the roller 19 to bear against the rotating cam plate 80.

A clutch mechanism M, the operation of which 10 is controlled by a manually operated leverv 85 (Fig.- 1) serves to throw the shaft 8i into or out of operative driving relation with a drive shaft 86 which receives its rotary motion from a jack shaft 81 driven from the gear reduction device 48. 15

It is to be noted that during the simultaneous application of spiral bands to the tumblers, the two banding wheels E rotate in the same direction but the disk on the shaft 45 applies a right spiral while the disk on the shaft d6 applies a left 20 spiral band and vice versa during alernate decorating operations. If both bands are of uniform color, it is obvious that successive tumblers issuing from the machine will be uniformly decorated. Where contrasting colors are employed, 25 alternately discharged tumblers will be uniformly decorated.

During the decorating operation both banding disks E dip into the enamel composition in the reservoir D and the disks become coated in their 30 peripheral regions. The enamel composition adhering thereto is transferred to the tumblers by contact of the edge of the disk to the latter. In order that the decorating operation may commence precisely at the moment when the disk 35 on the shaft 35 contacts the tumbler and in order that the enamel composition shall at all times be more or less evenly distributed on the periphery of the disk, the jet 52 discharges air against the turbine 6i continuously. 40

When it is desired to band the tumblers T uniformly with either'a single right or left spiral band, the bearing plates l8 (Fig. l) are removed; the shafts 45 and 46 are connected together and driven in unison by a suitable belt and pulley 4 connection at as shown in Fig, 5, while at the same time the supply of air to the Jet 52 is discontinued. The frame C is thus pivoted to the brackets it? by the floating connection provided by the pin and slot connection i9, 26. 50 The tumblers are alternately decorated on the two disks E by shifting the position of the frame C after each decorating stroke from the full line position to the dotted line position and vice versa. In both instances a right spiral band as 55 shown in Fig. 11 will be applied to the tumbler.

The application of left, spiral bands to the tumblers as shown in Fig. 12 is accomplished with the same machine set-up just described and may be attained merely by reversing the se- 30 quence of tumbler application to the disks E.

The application of parallel spiral bands of contrasting colors as shown in Fig. 8 is likewise accomplished with the same machine set-up with difierently colored enamels in the containers 38 65 and 3?. It is merely necessary to allow each tumbler to remain in the machine for a second color application, i. e., the two disks E are caused to operate successively on each tumbler, the disks being situated on their respective shafts 45 and 70 as in a position calculated to give the desired band spacing.

The application of an interrupted spiral band as shown in Fig. 9 may be accomplished by the incorporation in the machine of a plate OI (Fig. 6) 15 which is secured to the sliding rack bar Q2. The plate I is provided with a series of frame lifting cams 92 which, upon operative decorating travel pfthelbar I, successively engage the underneath .a side of the frame C and momentarily elevate the same to remove the tumbler undergoing decoration from contact with the banding disk E.

By employing the bearing plates l6 and thus shit 10 tom ers T contact the peripheries of both banding disks when the same are interconnected as shown by the broken line position of the tumbler in Fig. 5, and by disengaging the clutch mechanisml, closed bands of diflerent colors may be applied-to'thc tumbler as shown in Fig. 1a. A f

single band may be applied to the tumbler by shitting the position of the frame C so that the tbler engages the periphery of a single disk E regardless oi which one it may be. 2o Modifications may be resorted to within the spirit and scope of the appended claims.
